Generalised Gibbs Ensembles from the ODE/IM Correspondence: the Lee--Yang Model
Sujay K. Ashok, Max Downing, Faisal Karimi +2
We introduce a systematic scheme for constructing the ODE/IM counterpart of generalised Gibbs ensembles, and apply it to the chiral sector of the Lee--Yang conformal field theory.…
Universal Modular Properties of Generalized Gibbs Ensembles and Chiral Deformations
Sujay K. Ashok, Tanmoy Sengupta, Adarsh Sudhakar +1
We study modular properties of conformal field theories perturbed by holomorphic fields. We prove an asymptotic formula for the modular S-transform of a generalized partition funct…
Thermal Correlators and Currents of the Algebra
Sujay K. Ashok, Sanhita Parihar, Tanmoy Sengupta +2
Two dimensional conformal field theories with the extended symmetry algebra have an infinite number of mutually commuting conserved charges, which are referred to a…
Gravitational Poisson brackets at null infinity compatible with smooth superrotations
Miguel Campiglia, Adarsh Sudhakar
Superrotations are local extensions of the Lorentz group at null infinity that have been argued to be symmetries of gravitational scattering. In their smooth version, they can be i…
Integrable Structure of Higher Spin CFT and the ODE/IM Correspondence
Sujay K. Ashok, Sanhita Parihar, Tanmoy Sengupta +2
We study two dimensional systems with extended conformal symmetry generated by the algebra. These are expected to have an infinite number of commuting conserved ch…
The Radiative Phase Space for the Dynamical Celestial Metric
Adarsh Sudhakar, Amit Suthar
Generalized BMS (gBMS) is the Lie group of the asymptotic symmetries at null infinity, and is proposed to be a symmetry of the quantum S-matrix. Despite much progress in understand…
